Searching for TESS Photometric Variability of Possible JWST Spectrophotometric Standard Stars
Susan E. Mullally, G. C. Sloan, J. J. Hermes +7
We use data from the Transiting Exoplanet Survey Satellite (TESS) to search for, and set limits on, optical to near-infrared photometric variability of the well-vetted, candidate J…
A Temporal Scale to Track the Spectral Transitions in Low-Mass X-ray Binaries
E. Sonbas, K. Mohamed, K. S. Dhuga +1
The results of a temporal analysis of observations for a sample of nine low-mass X-ray binaries (LMXBs) are presented. Of these sources, five host a neutron star (NS) primary (4U16…
A Minimal Timescale for the Continuum in 4U 1608-52 and Aql X-1
K. Mohamed, E. Sonbas, K. S. Dhuga +4
Similar to black-hole X-ray binary (BHXRB) transients, hysteresis-like state transitions are also seen in some neutron-star X-ray binaries (NSXRBs). Using a method based on wavelet…
A Minimal Time Scale for the Spectral States of GX 339-4
E. Sonbas, K. Mohamed, K. S. Dhuga +2
Black hole transients are known to undergo spectral transitions that form q-shaped tracks on a hardness intensity diagram. In this work, we use archival RXTE data to extract a char…
